2 Claims.

The invention relates to a drop-preventing device, and is constructed inthe form of a spout to be used on bottles or similar receptacles. In thecase of all contrivances known up to now, no provision at all has beenmade to prevent the developing of drops when the bottle is raised to anupright position again, after having been inclined in order to pour outthe liquid, or, at least, this result has only been partly attained.Other contrivances, which are constructed so as to catch drops havingdeveloped during the process of pouring out the liquid, have thedisadvantage that a considerable quantity of the liquid being poured outis lost, after having absorbed Ward direction and is preferably inclinedtowards the outside in a downward direction, so that its limitedadhesive surface practically renders the developing of drops and theflowing down of liquids along the neck of the bottle impossible.

The drawing shows a working example of the contrivance which has beenmade the subject of this invention. It shows in Fig. 1 the contrivancein longitudinal section according to the line I-I of the Fig. 2.

Fig. 2 the contrivance in top view.

Fig. 3 the contrivance in side elevation.

Figure 4 is a fragmentary detail sectional view showing the upwardinclination of the bottom face of the annular rib or ring flange.

The device consists of an upper part a and a lower part b, which areseparated by an annular rib d.

The bottle spout should preferably be constructed entirely as a pressedor drawn piece with the middle annular rib d, which is set or rivetedon. Part b is fitted with a jacket, which is adapted according to thesize of the opening of the bottle and should preferably be taperedtowards the lower end and manufactured from cork etc. The upper part aends atthe top in an annular rib or drop-holding flange c, which isinclined in an outward direction. It is advisable that this annular ribis inclined in an outward and downward direction. At the same time, thelower face of the annular rib will preferably be inclined in an upwarddirection towards the neck of the bottle as shown in Figure 4. The upperedge of part a. can be constructed either 5 with sharp edges as is shownin the working example on the illustration or rounded. The annular rib ashould be narrow. Thus, a limited adhesive surface is created whichpractically renders impossible the developing of drops and the flowingdown of liquid along the neck of the bottle. In so far as drops have notyet been distributed over the upper surface of the flange c by means ofthe effect of adhesive power, such particles of liquid as have developedinto a drop can run only to the lower part of flange c, which, in thesame manner as the upper part, exercises an adhesiveand distributinginfluence upon the drop. As the lower face of the flange c is inclinedin an upward direction towards the centre of the opening from which theliquid is poured out, it is not possible for the liquid to flow farther.Owing to the capillary effect between the upper and the lower part ofthe annular rib or holdingflange c, suction is exercised on the liquidin an 5 upward direction so that in conjunction with the adhesive powerof the surface of the annular rib distributes and spreads any drop, thusexercising greater holding power over the same.

What I claim is:

1. In a drop-preventing device in the form of a spout to be used onbottles, a tubular spout, a relatively narrow ring flange at the openingof the spout arranged in an outward direction with its upper surface offrusto-conical formation and its lower surface inclined in a downwarddirection towards the outer edge of the ring flange, the limitedadhesive surface of said flange practically rendering impossible thedevelopment of drops and a flowing of the liquid in a downward directionalong the neck of the bottle.

2. In a drop-preventing device in the form of a spout to be used onbottles, a tubular spout, a relatively narrow ring flange at the openingof the spout arranged in an outward direction with 5 its upper surfaceof frusto-conical formation, the ring flange also at its underside beinginclined in an upward direction from the outside towards the neck of thebottle defining a relatively sharp marginal edge for the ring flange.
